Oceanography and Marine Biology by R. N. Gibson,R. J. A. Atkinson,J. D. M. Gordon Pdf
With increasing interest in the field and its relevance in global environmental issues, Oceanography and Marine Biology: An Annual Review provides authoritative reviews that summarize results of recent research in basic areas of marine research, exploring topics of special and topical importance while adding to new areas as they arise. This volume, part of a series that regards the all marine sciences as a complete unit, features contributions from experts involved in biological, chemical, geological, and physical aspects of marine science. Including a full color insert and an extensive reference list, the text is an essential reference for researchers and students in all fields of marine science.

Volume 25 of this authoritative review series continues the high standard set by the editors in the past. Marine biologists everywhere have come to value and enjoy the wide variety of thought-provoking papers written by invited experts. In this volume are reviews of four animal groups which span the entire range of the marine food chain. The role of parasites in ecology is a growing interest and the parasites of zooplankton are described in detail for the first time. Aspects of thegastropods, cephalopods and fish life are also examined in detail.
Incidental catch of vulnerable species in Mediterranean and Black Sea fisheries – A review by Carpentieri, P., Nastasi, A., Sessa, M., Srour, A. (eds.) Pdf
Bycatch – a term widely used to refer to part of the catch unintentionally caught during a fishing operation, in addition to target species, and consisting of the discards and incidental catch of vulnerable species – is considered one of the most important threats to the profitability and sustainability of fisheries, as well as to the conservation of the marine environment and ecosystems. Understanding the bycatch issue and adopting effective measures in order to reduce bycatch rates are essential steps towards minimizing the impacts on vulnerable species and ensuring both a sustainable fisheries sector and healthy seas. In the Mediterranean and the Black Sea, the incidental catch of vulnerable species – namely seabirds, sea turtles, elasmobranchs, marine mammals and macrobenthic invertebrates – represents one of several challenges for the industrial, semi-industrial and small-scale fisheries that coexist in the region, as well as for the diverse and sensitive ecosystems impacted. Typically, data on this issue have been collected in an opportunistic manner and in ways that make comparisons difficult. The annual absolute values of incidental catch of vulnerable species are not available: studies cover only a small portion of the total fishing activity and often present important knowledge gaps for many types of fishing gear, countries and/or subregions, as well as on temporal scales, for example, to establish reliable baselines. The result is that little is known of the scope of the problem, despite incidental catch being a significant pressure on the populations of vulnerable species, as well as a concern for fishers.This regional review is an attempt to compile, in one single document, all available data and historical records on the incidental catch of vulnerable species in the Mediterranean and Black Sea fisheries, obtained from existing literature, databases and other grey sources, and collated in a standardized and comparable way. The main objective is to provide comprehensive baseline information, earmark the main data gaps, as well as identify the most impacting types of fishing gear by taxonomic group. This work is a reminder of the importance of standardized data collection and the need to have baseline information in order to support decision-making in the identification of appropriate bycatch mitigation techniques, thus enabling analysis of their effectiveness and comparison over time and space, as well as facilitating the implementation of relevant conservation and/or management measures at the national, subregional and regional levels.
This special volume of Advances in Marine Biology covers in detail the biology of calanoid copepods. Copepods are probably the most numerous multicellular organisms on earth. They are aquatic animals that live in both marine and fresh water, and are of prime importance in marine ecosystems as they form a direct link between phytoplankton and fish. This volume is essential for all marine biologists. Advances in Marine Biology contains up-to-date reviews of all areas of marine science, including fisheries science and macro/micro fauna. Each volume contains peer-reviewed papers detailing the ecology of marine regions.
Post-Embryonic Development of the Copepoda by Frank D. Ferrari,Hans Uwe Dahms Pdf
The first monograph to compile observations about the post-embryonic development of the morphologically and ecologically diverse subclass Copepoda. Analyses provide insights into the correspondence of developmental stages among species, architecture of the naupliar body, and patterning of copepodid body and limbs.
Non-indigenous species in the Mediterranean and the Black Sea by Food and Agriculture Organization of the United Nations Pdf
Recent decades have seen significant changes in the biota of the Mediterranean and the Black Sea due to the introduction of non-indigenous species. Reliable scientific data on the dynamics of their distribution and abundance are essential to understand their ecological and economic effects. This review – in addition to providing images and descriptions of relevant species to aid in identification – presents a unique historical and regional perspective on these species’ impacts, based on many years’ worth of research. The Black Sea’s primary invaders come from the Mediterranean. Species like the comb jelly Mnemiopsis leidyi have caused major declines in biodiversity in the region by crippling key segments of the food chain. Similar results have been noted in the Marmara Sea, a crucial water exchange point located between the Aegean Sea and the Black Sea. Infiltration into the Mediterranean comes from both the east and west – with Lessepsian species passing through the Suez Canal and fish and invertebrate species originating from the Atlantic expanding their ranges. As of the publication of this review, over 900 non-indigenous species have been reported in the Mediterranean and almost 300 in the Black Sea, with these numbers expected to rise in the future. Numerous Lessepsian fishes are commercially relevant and have been absorbed into local markets, particularly in the eastern Mediterranean region. While these species are targeted through various fishing techniques, many others are simply discarded due to a lack of value and there are even some, such as lionfishes, pufferfishes and several species of jellyfishes, that present immediate dangers to human health. Stewardship of native species, regional cooperation on the enforcement of legal measures, increased public awareness and the creation of marine protected areas are thus essential to minimize and reduce the impacts of non-indigenous species both in the Mediterranean and the Black Sea.
Contributions to the Life Histories of Several Penaeid Shrimps (Penaeidae) Along the South Atlantic Coast of the United States by William Wyatt Anderson Pdf
Bridging Divides by Stephan Gollasch,Bella S. Galil,Andrew N. Cohen Pdf
Maritime canals dissolve natural barriers to the dispersal of marine organisms, providing novel opportunities for natural dispersal, as well as for shipping-mediated transport. This book is the first to assess the impacts of the world’s three principal maritime canals – the Kiel, the Panama, the Suez – as invasion corridors for alien biota. These three canals differ in their hydrological regimes, the types of biotas they connect, and in their permeability to invasions.
